Appncation 1eiefi March 27, 1909. seriai N0. 486,065.

To all whom t may concern? Be it known that I, RALEIGH I SLEEVE, a citizenv of the United States, residing in the borough ofn Manhattan, in the city and Stateof New York, have invented certain new and useful'lmprovements in Coolers or Like Apparatus, ot which the following is a specification. y l Myinvention has for its object an im proved construct-ion of coolers, or, as they are sometimes called, radiators, and while applicableto various uses, theparticular application of my invention is to radiate heat from the cooling water of anr internal com` bustion engine, as, for instance, on automobiles. v

in the. practice of my invention l obtain aA cooler which is eilicient, simple of manufacture Aparticularly in the assembly, land in-,

creased strength of construction, while maintaining or increasing the other features of advantage ot' existing constructions ot articles of this character.

In the accompanying ldnawings forming a part hereof, l have shown a particular form of embodiment of my invention, which is specifically described as follows:

Figure 1 is a front elevation of acooler partly broken -away and partly shown in.

section;v F ig. 2 is a perspective ,view of a component section of my cooler; Figflis a transverse section ot' one ribv of a section;

Fig. Bb'is the end view of one rib and Fig. is a section of one rib of a modified form.

In the drawings AA are sections which are put together to form the radiator as,

f be held together during the process oi as* sembly by any suitable means, as punching lshown part brokengaway in Fig. 1.

voverlapping offset ends of-opposed- )lates of 'adiacent sections A, which turnsV -over ends and P may be brazed, soldered or otherwise secured.

C is in eiect a top partition formed by the overlapping of oisets from the upper ends of adlacent sections, which are likewise s`ecured in any suitable manner.

c is the top of the casing, D are the sides of the casing, E is thebottoin of the casing, F is a front cover secured to the side walls and the top wall and the bottom, and secured around its inner edge to the sections or body portion ofy the radiator. This junc- -tion of side walls, ltop and bottom and the l C. vGILBER-y and Ia "water-space at the lower portion ot the radiator, while any suitable connectionslead to the rear of the top space and Ifrom i the rear of the bottoml space to the waterjacket of the engine, or other source of heated water or steam to vbe, cooled. The spaces Gbetween the walls or" each section A form a vertical passage from the top water-space to the bottom water-space.

The sections A. consist of a plate a which is stamped to the form as show-n in sectionA in Fig. 2.

a is a plate which is crimped at frequent intervals and each crimp is then closed on -itself forming the ribs or shelves g at right angles to the body of the plate a. These shelves or Voffsets have their edges turned down as at L- for the full length except a short distance at each end y'. Instead ot' turning down the edge, the shelt` or horizontal projection may be crimpedas shown at lli in Fig. 3,, for their entire lengt-h with the exception of a short distance 7' at either end.

The section plate a may have vertical or other projections as m, which,l serve to separatel it from the main body of the plate o', while the/ends n of the plate a are bent so' as to contact with the plate a', to the same extent as the depression of t-he corrugation m. When placedv against the plate a', the plate a, ,will form a'clear space G running' from top to bottom of the section, of a suitable depth oi width, to permit Water to flow through it, while the edges on either side will be closed. These edges, where the side n of the plate a touches the plate e', may

or bending the edge', after which the. suit able number ot complete sections, such as A, are stacked together to form the `main body port-ion of the radiator. When so assembled the edges are dipped in a bat-li of solder or spelter, or by any other suitable method they are united, which permanently secures the edges of the two plates in each section, and furthermore secures the edge j of the lateral shelves or 'ribs on each sect-ion to the back plate a. of the adjoining section at the depression n. A lt will be seen that the edge'h of the lateral partitions g isturncd over just enough to accommodate' the thicknessor depthof the offset of plate a from plate a. In this way each partition may have along the it.. t

turned over edge It of its offsets, a bearing against a plate a, while cach end of the lateral odset g is brazed orsoldered to the adjoining section. This results in an interconnection of sections, giving reat stiffness and solidity ofthe radiator bo y as a. whole. The arrangement and fashioning of parts likewise leave rectangularspaces between the middle, as shown at k in Fig. 3c, still leaving the end' j of the required width so as to Contact with the front and rear edge n n of the adjoining section to which it is then secured.

` 4As shown in Fig. 1, a section A is shown cut away a short distance in from the forward edge disclosing the passage G and the lateral projections with their turned over edges, while at P andv P the lower endsof the plates a and a are shown turned over to form in e'ect a bottom plate B, so that the lower water-space of the radiator is connected to the passage G.'

The upper end of the plate a of each section is turned over as shown at k', overlapping the turned over end of the plate a of the adjoining section to which it is soldered or brazed, or otherwise secured, to form a water-tight joint. The parts of sect-ion a may be made in more or less continuous strips and cut to lengths, so that the ribs may be employed to serve as the top and bottom offsets 1n place of the plain bent end shown at P. In either'case the material of the two walls forming a section a are bent apart at the upper end and lower end, -thereby leaving the passage G open, and the ,neighboring top and bottom flanges are united in any suitable manner to form a water-tight joint. VWhen this central or body sectiono the radiator is complete, attachment to it of the front plate F, and the attaclnnent of asimilar plate to the rear, forms a water-tight joint, thereby closing the upper waterlspace and the bottom waterspace. By this arrangement I eliminate the necessity of top and bottom plates to which the sections would otherwise be secured. Y

From the above the method of construction will be understood, and it will beseen that when assembled and secured together the resultant construction presents a series tangular openings the air can readily pass,

making the interiorwalls an effective radiating surfaoe. i

It .will also be noted that in the practice of my invention simplicity and economy of construction are effected by the elimination of parts in the construction, which otherwise would be required, as, for inst-ance, separate top and bottom plates, and results in a very strong and simple method of construction.

Various modifications and details of oonstruction and methods of manufacture may be used without departing from the spirit of my invention, and I do not wish to co'nne myself to the precise form herein shown and described, but

What I claim ters Patent is:

1. A cooler composed of sections, each section comprising two plates suitably spaced by means of ribs on one of the plates, a series of transverse spacing o'sets on the other of said plates, each offset being provided with a crimp whereby the projection of the other plate on the adjacent section is accommodated. v v

2. A cooler composed ,of sections each comprising two plates suitably spaced and with joined edges alongtwo sides, a series of transverse ribs formed by offsetting the material of one of said plates, a crimp along the edge of each rib extending the full length with the exception of the two ends.

3. A section of a cooler comprising two plates, depressions on one of said plates, a closed joint at two opposite edges of said plates, transverse projections extending from edge to edge of one of said plates, a bent over portion of said lateral projection extending from close to one end to c the other end substantially as and for the purpose described. i

4. Sections for radiators, or coolers, comprising a portion of a longitudinalribbed sheet metal strip as one wall, and having and desire to secure by Let.

'for the other wall'a sheet metal strip with -transverse off-sets, eachof said offsets being bent back upon itself, and a portion of each of said offsets being bent parallel to the main body portion of said sheet to form a rigid truss.
